ISO 11024-1:1998

Essential oils -- General guidance on chromatographic profiles -- Part 1: Preparation of chromatographic profiles for presentation in standards

This part of ISO 11024 describes general guidelines on the determination of the chromatographic profile of an essential oil by gas chromatography on a capillary column.

The chromatographic profile is one of the specifications which enables assessment of the quality of an essential oil in the same way as the physico-chemical characteristics. It is determined at the time of finalizing the standard on the essential oil.

It is not a determination of the true concentration of the components, it is only an evaluation of its relative proportions.
